Description

Technical Field

[0001] This utility model relates to the field of belt drive technology, specifically to a belt dehumidification device. Background Technology

[0002] In existing sludge treatment technologies, belt conveyors are often used to transport materials. However, the high temperature and humidity inside the sludge treatment plant create a temperature difference with the outside environment. Current belt conveyors lack internal dehumidification devices, causing indoor water vapor to condense rapidly upon contact with the cold air, adhering to the inside of the belt. This condensation reduces the friction between the belt and the rollers, leading to slippage when the inner belt contacts the rollers, affecting the stable operation of the equipment. Excessive humidity results in frequent belt slippage, making maintenance difficult and time-consuming, and in severe cases, even causing the entire workshop to shut down, impacting production speed and efficiency. Furthermore, prolonged belt slippage causes localized wear, affecting the service life of both the belt and the rollers.

[0003] Therefore, there is an urgent need for a belt dehumidification device that can dehumidify the belt and ensure its smooth operation. Summary of the Invention

[0004] This invention addresses the problem of slippage and production disruption caused by existing belt conveyors in humid environments by providing a belt dehumidification device. This device removes condensate adhering to the inside of the belt, keeping the connection between the belt and the roller dry, thereby restoring the belt to its original friction and ensuring stable operation of the equipment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A belt dehumidification device is applied to a belt conveyor, the belt conveyor including a drive roller, a driven roller and a conveyor belt, the dehumidification device including a wind box, an air storage tank and a monitoring and control unit, the wind box being located between the upper and lower surfaces of the conveyor belt and fixed on the frame of the belt conveyor, the wind box having an air outlet on the side facing the conveyor belt, the air inlet of the wind box being connected to the air storage tank through an air supply pipe, and a valve being installed on the air supply pipe;

[0007] The measurement and control unit includes a humidity sensor and a controller. The output of the humidity sensor is connected to the input of the controller, and the output of the controller is electrically connected to the valve. The humidity sensor monitors the ambient humidity and generates a humidity electrical signal, which is fed back to the controller. The controller controls the valve based on the received humidity electrical signal.

[0008] Furthermore, the bellows box is triangular prism in shape, with one end closed and the other end having an air inlet. A long, narrow air outlet is located on one side edge of the bellows box. High-pressure gas forms an air knife at the air outlet, and the thrust of the air knife removes condensate adhering to the inside of the belt, thereby restoring the belt to its original friction and ensuring equipment operation.

[0009] Furthermore, the air storage tank is connected to an air compressor, which compresses air in the environment and supplies it to the air storage tank. The air storage tank provides a stable air source for the bellows.

[0010] Furthermore, the controller has a preset humidity value. When the ambient humidity exceeds the preset humidity value, the controller controls the valve to open; when the ambient humidity is lower than the preset value, the controller controls the valve to close.

[0011] Furthermore, the valve includes a solenoid valve, and the controller is a programmable logic controller (PLC).

[0012] Furthermore, the dehumidification device includes at least two air boxes, one located at the feed end of the driving roller and the other at the feed end of the driven roller. This prevents the damp inner side of the belt from contacting the roller and causing slippage.

[0013] The beneficial effects of this utility model through the above technical solution are as follows:

[0014] This utility model is equipped with a wind box, an air storage tank, and a measurement and control unit. A humidity sensor monitors the ambient humidity, and the controller controls the air storage tank to supply compressed air to the wind box based on the received humidity electrical signal. The high-pressure gas forms an air knife at the air outlet, and the thrust of the air knife removes the condensate adhering to the inside of the belt, thereby restoring the belt to its original friction and ensuring the operation of the equipment.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-4 As shown, this embodiment provides a belt dehumidification device applied to a belt conveyor. The belt conveyor includes a drive roller 3, a driven roller 1, and a conveyor belt 2 disposed on the surface of the rollers. The belt conveyor is driven by a motor.

[0022] The dehumidification device includes a blower box 4, an air storage tank 7, and a measurement and control unit. The blower box 4 is used to remove condensate water adhering to the inner side of the belt 2; the air storage tank 7 is used to store compressed air and provide a stable air source for the blower box 4; and the measurement and control unit is used to adjust the intensity and timing of the blowing.

[0023] The air box 4 is located between the upper and lower surfaces of the conveyor belt 2 and is fixed to the frame of the belt conveyor. The air box 4 has an air outlet 42 on the side facing the conveyor belt 2, and the air inlet 41 of the air box 4 is connected to the air storage tank 7 through the air supply pipe 5. The air storage tank 7 is connected to the air compressor 6, which compresses the air in the environment and supplies it to the air storage tank 7 and the air box 4.

[0024] like Figure 2 As shown, the bellows 4 has a triangular prism shape. One end of the bellows 4 is closed and the other end is provided with an air inlet 41. A long strip-shaped air outlet 42 is provided on one side edge of the bellows 4 to form a strip-shaped air outlet. The air outlet 42 of the bellows 4 is at an angle to the belt 2. The high-pressure gas blown out from the bellows 4 removes the condensate water adhering to the inside of the belt, thereby restoring the belt to its original friction and ensuring the operation of the device.

[0025] Specifically, the air box 4 is fixed to the frame of the belt conveyor by a bracket. The length of the air box 4 is not less than the width of the conveyor belt 2. The air outlet 42 of the air box 4 faces the inner side of the belt 2, and there is a gap between them. The dehumidification device includes at least two air boxes 4, one of which is located at the feed end of the driving roller 3, and the other is located at the feed end of the driven roller 1. The air outlet 42 of the air box 4 is close to the connection point where the belt 2 enters the roller 3. Figure 1 The image shows two bellows 4.

[0026] A valve 11 is provided on the air supply pipe 5. The valve 11 controls the airflow of the air box 4 and adjusts the intensity and timing of the blowing. Specifically, the valve 11 includes a solenoid valve. As one possible implementation, a solenoid valve with model number N4V210-08 produced by Zhejiang Chint Electric Co., Ltd. can be used.

[0027] To control valve 11, valve 11 is connected to a monitoring and control unit, which includes a humidity sensor 9 and a controller 10. The output of the humidity sensor 9 is connected to the input of the controller 10, and the output of the controller 10 is electrically connected to valve 11. The humidity sensor 9 monitors the ambient humidity and generates a humidity electrical signal that is fed back to the controller 10. The controller 10 has a preset humidity value. When the ambient humidity exceeds the preset value, the controller 10 controls valve 11 to open; when the ambient humidity is lower than the preset value, the controller 10 controls valve 11 to close.

[0028] Specifically, such as Figure 4 As shown, the valve 11, controller 10 and humidity sensor 9 are electrically connected. The controller 10 includes a programmable logic controller (PLC). The controller 10 controls the valve 10 according to the received humidity electrical signal. The model and connection method of the controller 10 are shown in the figure.

[0029] The working principle of this utility model:

[0030] When in use, after the belt conveyor is turned on, the humidity sensor 9 detects the ambient humidity. When the ambient humidity exceeds the preset humidity value, the controller 10 controls the valve 11 to open. The high-pressure gas in the air tank 7 is delivered to the air box 4 through the air supply pipe 5. The high-pressure gas forms an air knife at the air outlet 42. The thrust of the air knife removes the condensate adhering to the inside of the belt 2, thereby restoring the belt to its original friction. During this process, the air compressor 6 compresses the air in the environment and supplies it to the air tank 7.
